Well God did create the sun and moon for a purpose, but their purpose was help people determine his holy days:
(GW) Then God said, "Let there be lights in the sky to separate the day from the night. They will be signs and will mark religious festivals, days, and years
But I think this prognostication based on "blood" moons is pretty far fetched. It's safe to say that the holy days of the Lord can and do herald significant events which of course is part of the reason for their creation.
I tend to agree, but don’t recall the verse you mentioned in that form. Can you cite it?
We indeed live in exciting times wherein solar eclipses fascinate the sense of ourselves as living in the universe. At least as long as they last.
In that such a totality also brought Einstein confirmation of more distant starlight being bent along the gravitational field of the sun, lends such perfect alignment the whiff of Divinity.
But even these events take place against the larger cosmic backdrop. These may be interesting for study, but always with an eye as to how they contribute to the whole. And therein the sole focus of worship should be on the Almighty, and not merely those aspects of His invention.
